Translation of L'évolution du vivant. An introduction to the study of evolution : General observations on the living world ; Biological evolution and its occurrences ; Interpretation of evolutionary ...

Beneficial mutations happen quite frequently, but the world changes too fast for them to stick.

Tuberculosis is the world's deadliest infectious disease, due in part to its ability to hide out for years in the lungs before starting an infection. Now, a new computational method developed by ...

How will life on Earth and the ecosystems that support it adapt to climate change? Which species will go extinct – or evolve into something new? How will microbes develop further resistance to ...

Evolution is traditionally associated with a process of increasing complexity and gaining new genes. However, the explosion of the genomic era shows that gene loss and simplification is a much more ...

Forbes contributors publish independent expert analyses and insights. Andréa Morris reports on emergent intelligence in diverse systems. “Where are all the genetic cures?” asks Denis Noble, a ...

Every organism responds to the world with an intricate cascade of biochemistry. There’s a source of heat here, a faint scent of food there, or the crack of a twig as something moves nearby. Each ...

The molecular clock theory posits that genetic changes happen steadily and gradually, offering a reliable means for peering into the past and theorizing when complex life first emerged. However, there ...

We typically think of evolution as progressing in one direction, with a species getting “better” and “better” as it goes. But evolution is far more complex than that, as has recently been illustrated ...

A scientist from Protein Evolution works in the company's New Haven, Connecticut, facility. In nature, mutations are introducted randomly into organisms. The strongest ones survive. Protein Evolution ...
